Methods A prospective randomized controlled study was conducted. The used endoscopes were divided into automatic group and manual group by random number table method, 200 in each group. In the automatic group, the AFECBS was used to scrub each tube 3 times during endoscope cleaning and in the manual group, scrubbing and disinfection personnel routinely brushed each pipeline for 3 times. The primary end point was the qualified rate of endoscopic cleaning quality in the two groups, and the secondary end point was the time spent by the scrubbing and disinfection personnel on the two groups. Results The qualified rate of overall cleaning in the automatic group was 90.0% (180/200), and in the manual group was 81.0% (162/200). The qualified rate of the automatic group was higher than that of the manual group (χ2=6.534, P=0.011). The qualified rate of gastroscope cleaning in the automatic group was higher than that in the manual group [92.0% (127/138) VS 81.6% (120/147), χ2=6.658, P=0.010]. There was no significant difference in the qualified rate of colonoscope cleaning between the automatic group and the manual group [85.5% (53/62) VS 79.2% (42/53), χ2=0.774, P=0.379]. When the cleaning personnel scoured 5 endoscopes in each of the two groups, the time of the automatic group (5.17±0.42 min) was shorter than that of the manual group (9.60±0.53 min) (t=92.644, P<0.001). Conclusion Compared with manual scrubbing, AFECBS can improve the qualified rate of endoscope cleaning and the work efficiency of scrubbing and disinfection personnel, which is worthy of clinical application.

The compound endoscopic dissection knife can readily switch between Dual knife mode and IT knife mode. Vitro experiments were done on 30 mucosal lesion models and 30 submucosal lesion models, respectively, of pig stomach tissue. In vivo experiments, mucosal lesion resection were performed on each 10 lesions of gastrointestinal tract in 6 porcine models. The compound endoscopic dissection knife were used in the experimental group, and Dual knife combined with IT knife were used in the control group. Dissection time were recorded. The wounds were biopsied to evaluate muscle damage. The results of vitro experiment showed the dissection time of mucosal and submucosal lesions in the experiment group was significantly shorter than that in the control group (17.93±2.52 min VS 21.07±3.58 min, t=-2.774, P=0.010 25.73±2.66 min VS 31.80±3.78 min, t=-5.081, P<0.001). The results of vivo experiment showed the dissection time in the experiment group was significantly shorter than that in the control group (21.67±4.10 min VS 25.36±3.83 min,t=-3.602, P=0.001). The muscle damage rate was lower in the experimental group, but the difference was not statistically significant [3.3% (1/30) VS 10.0% (3/30), χ²=1.071, P=0.612]. The compound endoscopic dissection knife is both safe and effective in animal models.
